New member and just received my 9s, ser # 33xx, built December 12th. Because of this forum I had Aluminum grips waiting with new screws and recoil springs. I already knew how to take it down and put it back together with all the tricks I learned.
Most important was the good info on the grip removal, lucky I read how to put a sharp edge under the grips to remove them because I might have used a blow torch as they were tight!
Will shoot it Sunday at the range and will let you all know how it went. A BIG THANK YOU TO ALL FOR ALL THE GREAT INFO!
